c++ Programming Glossary: copyinsertableWhy does reallocating a vector copy instead of moving the elements? [duplicate] http://stackoverflow.com/questions/10127603/why-does-reallocating-a-vector-copy-instead-of-moving-the-elements is thrown other than by the move constructor of a non CopyInsertable type there are no effects. And the description of resize in.. in §23.3.6.3 12 requires the same. This means that if T is CopyInsertable you get strong exception safety. To assure that it can only.. will be necessary or sufficient for that though. If T is CopyInsertable it can simply choose to always use copy construction. Basically..
